PT-407 pressure sensor Refrigeration and ventilation Special for pressure transducer

Refrigeration and ventilation pressure sensor------As a pressure transmitter specially developed for the refrigerant industry, PT-407 incorporates the piezoresistive sensor core of a well-known brand company, combined with high-reliability amplification circuit, precision digital temperature compensation and non-linear correction technology. Its design goal is to convert the pressure of the measured medium into reliable 4~20mA and 0~5VDC analog signals.

PT-407 pressure transmitter has a unique anti-condensation design, which effectively prevents water vapor in the sensor cavity from condensing and damaging the circuit board. This design ensures long-term stability and reliability in harsh environments. Whether in the refrigeration industry such as air conditioners, refrigerators, freezers or water-cooled screw units, PT-407 can be widely used.

High stability is a major feature of the PT-407 pressure transmitter. Through advanced technical means and careful debugging, the product can operate stably and permanently, ensuring the accuracy and reliability of pressure measurement data. Users do not need to worry about frequent calibration or maintenance, saving time and labor costs.

 pressure transmitter - a high-stability, cost-effective product dedicated to the refrigeration industry

At the same time, the PT-407 pressure transmitter has the advantage of high cost performance and provides an economical solution for the refrigeration industry. Compared with similar products, it is not only reasonably priced, but also has better performance and can meet users' requirements for accuracy and reliability in the refrigeration process. In addition, its ease of installation and use also reduces the difficulty of user operation and improves work efficiency.

In short, as a special product for the refrigerant industry, the PT-407 pressure transmitter has been widely used in refrigeration equipment such as air conditioners, refrigerators, freezers and water-cooled screw units due to its high stability, high cost performance and wide applicability. Whether it is a new project or the renovation of existing equipment, choosing PT-407 is a wise choice.
